owners are /. "A. Hall, who owns half, and
Mr.. Roberts and another man who have
the balance. Some money was paid on
the bond, and a force of men will be put
| at work very soon in developing the pro
| perty. 1t has been worked by tunnel and
shows a strong vein of high grade ore.
A MODEL SILVER MILL.
The milling plant of the Granite mine
near Philipsburg as described by the Butte
Inter Mountain is as perfect as can be found
in the world. 1t consists of the original
20-stamp mill constructed in the fall of
1884, increased to 80 stamps the follow
ing year, and the recently constructed 40
stamp mill in which the acme of perfec-
ton has been reached. Not only is the
machinery Of the latest and most improv-
ed pattern, but its arrangement is such
that for economic and satisfactory work
ings 1t cannot be surpassed. The 40
stamp mill is built on the mountain side
at the level of Tunnel Nc. 4 and immedi-
ately adjoining on the north the old mill.
To the erusher floor, which is situated
highest up the mountain. a tramway leads
from the mouth of the accompaniment
shaft through which the lower levels OF
the mine are worked.
From this floor the ore passes through
two immense Blake crushers into two CYL
indrical dryers from which it falls by
gravity into eight Tulloch automatic
feeders which supply the batteries. The
battery room is q marvel of cleanliness,
the suction flues being arranged that it is
absolutely free from dust. From this
| point the pulp is elevated to the rooster
! COO, where are situated two large
| Howell roasters. After roasting, the pulp
falls into an enormous bin from
| which 1t is drawn as needed on
the cooling floor. This portfono of the mill
is Manager Plummer's particular pride,
and we'll it may be. It is az clean as a
parlor; no dust, no dirt-in fact nothing
| but the strong odor of chlorine to denote
It's purpose. A capacious bin extends
| along the further side of this floor, In
which the pulp is allowed to cool from
| thirty-six to forty-sight hours. While
! slowly cooling chorination continues, and
| careful assays have demonstrated that the
! pulp is chloridized from two to four per
| cent. higher upon leaving these bins than
| were the rooster samples. From these bins
! the pulp is conveyed on cars on q steel
| track to the pan room, where are situated
| sixteen pans and eight settlers. From
| these settlers the amalgam is taken to the
| retort room, in which are six large retorts
| and the melting furnaces, which reduce
| the silver to the form of bars. The Granite
| mine has 335 men on its payroll, and is
1900 feet above the sea level. The stock
! has risen from $500 per share to about
80 times that sum. 1t is held chiefly in
So. Louis and there is netlmuch in the
market.
THE NEIHART CAMP.
John G. E.. Barker, superintendent of
the Hudson Mining company, says that
| the property is looking fine. Their con-
| centrator was put in operation on the Goth
ult., and proved highly satisfactory.
The Cumberland mine, a recent dis
covery in the Castle Mountains, about
twenty miles distant from White Sulphur
| Springs, which was bondedgtwo months
ago to Messrs. Ash s. King for $4,000,
is proving much better than was promised.
There are a!read quite a number Of pros
pectors in the Castle district, who have
made seme excellent discoveries. A town
named Castle has already been laid out
with one general store and two saloons as
a starter.
The Bourbon mine in the Birch creek
district, twelve miles distant from White
| Sulphur Springs has been bonded to Messrs
Barker 6 Edwards Of Butte, both ex-
perienced miners and possessed of ample
means for developing the property. This
mine was discovered in 1864, but having
| been in the hands of parties who were in
experienced, for a greater part of the
time, and who were not possessed of sufd-
cient money and grit to push develop
ment, it has lain idle. The gentlemen
who have the bond, however, are confident
It will prove a valuable property. They
have also a number of locations which
are being p%rospected.
